Kosai sits between Hamamatsu and Toyohashi in western Shizuoka. It is home to factories linked to the automotive industry, suppliers, staffing agencies, shops and many foreign families who started their own businesses. In companies of this size, there is almost never an "IT person". The owner, the owner's son or the employee who "knows a bit" fixes things. This guide shows how to organise IT in a small Kosai business and when professional support is worth it.
The minimum every company should have
Before thinking about new systems, make sure of the basics:
- Automatic updates turned on in Windows, macOS and phones.
- Antivirus active on every computer (Microsoft Defender already helps a lot if it is on and up to date).
- Automatic backups of important files, with one copy outside the office.
- Different passwords for each service and two-step verification on email and banking.
- One company email account per person, instead of everyone sharing the same login.
- A list of computers, accounts and who has access to what.
It sounds small, but most serious problems we see happen because one of these items was missing.
Signs it is time to call support
- You lose more than an hour a week fixing computer problems.
- Nobody knows the admin password for the router or email.
- Company files are scattered across USB drives, LINE and personal computers.
- An employee left and took access that nobody can change.
- You received a suspicious email or SMS and don't know if someone clicked.
- You are opening a new shop, hiring more people or changing systems.
What to ask from local IT support
A good provider in Kosai should be able to:
- Respond quickly remotely (remote access, phone, LINE or WhatsApp).
- Visit your business when the problem is physical, such as the network, a printer or a PC that won't start.
- Explain without jargon, in the language of the person using the equipment.
- Document everything: passwords stored securely, an equipment list and what was done.
- Prevent, with regular maintenance, not just put out fires.
A simple maintenance routine
If you want to start on your own, follow this calendar:
- Every week: check that the backup ran and whether updates are pending.
- Every month: review who has access to company email and folders; remove former employees.
- Every three months: test restoring a file from backup and change the guest Wi-Fi password.
- Every year: review licence, domain and hosting contracts so nothing expires.

A typical way to start
A common first step is an assessment: we look at the computers, network, accounts and backups, and hand you a list of what is fine, what is urgent and what can wait. From there, you decide whether to fix things yourself, hire us for part of it or leave everything to us.
Recent incidents in Japan, such as the Lawson ID data leak, show that customer data is a constant target. Small businesses are not off the radar just because they are small.
